FOOT EXERCISING APPARATUS
BACKGROUND OF THE INVENTION
The present invention relates to exercising
apparatus, and more specifically the present invention
relates to a mobile foot exercising apparatus for training ~
the muscles of the legs by sliding two foot plates on two ..
sliding rails alternati~ely. The drag resistance can be
adjusted according to the player's physical conditions. :
A variety of exercising apparatus have been
proposed for exercising different parts of the body, and have
appeared on the market. Regular exercising apparatus
which are specifically designed for exercising the legs are . ;~;~
commonly heavy, and occupy much installation space. .
Therefore, these exercising apparatus are not suitable for
personal use.
SUMMARY OF THE INVENTION I ~
Therefore, the main object of the present ~ .
~: invention is to provide an exercising apparatus for
exercising the legs which i~ lightweight, and which occupie~
' '~''
2091~
less installation space. It is another object of the
present invention to provide a foot exercising apparatus
which can be conveniently adjusted to produce different drag
resistance. -~
~,
According to the preferred embodiment of the
present invention, the foot exercising apparatus comprises
two foot plates mounted on two slides inserted in two floor
tracks, a first linking-up cable connected between the slides
and wound through a set of pulleys at the front, a second
linking-up cable connected between the slides and wound
through a set of pulleys at the back, and a damping wheel
controlled by a knob to adjust the drag resistance of the
second linking-up cable. Stop blocks are respectively
fastened to the slides to limit their moving range. Pin
bearings are arranged in the floor tracks to support the
slides for permitting the slides to be alternatively
reciprocated by the foot plates with the legs. Rollers
are fastened to the slides and supported on the floor tracks
to smoothen the reciprocating movement of the foot plates.

DETAILED DESCRIPTION OF THE P_EFERRED EMBODIMENT
Referring to Figs. 1 and 2, a foot exercising
apparatus in accordance with the present invention is
generally comprised of a front stand 10, a rear stand 20, a
10 chassis 25, two floor tracks 30, two slides 40, a pulley
assembly , a drag resistance regulating device, two locating
members 70, two stop blocks 75, two linking-up cables 80;81,
and two foot plates 90;91.
The front stand 10 is made from a hollow,
15 rectangular bar transversely disposed at the front, and
fastened with a top frame 12 having a unitary horizontal
plate 13 extended backwards in the middle and terminated to a
vertical plate 14 with a through hole 15. The rear stand
20 is also made from a hollow, rectangular bar transversely
20 disposed at the back in parallel with the front stand 10.

The chassis 25 is transversely disposed in the middle between
the front stand 10 and the rear stand 20, having a flat top
raised from two opposite lower ends thereof. The two
opposite lower ends of the chassis 25 are respectively
fastened to the floor tracks 30 at the bottom. The floor
tracks 30 are bilaterally connected between the front and
rear stands 10;20 at the top, each of which having a T-
channel 31 through the respective length respectively
fastened with a series of equally spaced pin bearings 32.
The slides 40 are respectively fitted into the T-channel 31
on either floor track 30 and moved to slide back and forth on
the pin bearings 32 alternatively. Each slide 40 has pairs
of rollers 41 supported above the top of the respective floor
track 3~0 to facilitate its reciprocating movement. The
pulley assembly is comprised of a first pulley 51 and a
second pulley 52 respectively mounted on the top frame 12 on
two opposite ends thereof, an adjusting wheel 53 mounted on
the horizontal wall 54 of an angle plate 55, which has a
screw rod 56 inserted through the through hole 15 on the
vertical plate 14 and locked by a nut 57, and a third pulley
58 and a fourth pulley 59 respectively mounted on the rear
stand 20 at the top by a frame 16 at locations corresponding
2091510 ~:
to the first and second pulleys 51;52 respectively. The
drag resistance regulating device is comprised of a damping
wheel 60 and a knob 61. The damping wheel 60 is mounted
on the chassis 25 at the top and turned by the knob 61 to
regulate the drag resistance of the apparatus. The
locating members 70 are respectively fastened to the slides
40 at an inner side. The stop blocks 75 are respectively
fastened to the slides 40 below the respective locating
member 70. One linking-up cable 80 has one end fastened
to the locating member 70 on either slide 40, and an opposite
end wound through the first pulley 51, the adjusting wheel
53, and the second pulley 52 in proper order, and then
fastened to the locating member 70 on the other slide 40.
The other linking-up cable 81 has front end fastened to the
locating member 70 on either slide 40, and an opposite end
wound through the third pulley 58 and the damping wheel 60,
then wound through the fourth pulley 59, and then connected
to the locating member 70 on the other slide 40. The
! foot plates 90j91 are respective fastened to the slides 40 at
~0 the top. When assembled, as shown in Fig. 1, the
apparatus is used for sliding the foot plates 90;91 with the
legs on the tracks 30.
2091510
The operation of the present invention is outlined
hereinafter with reference to Fig. 3. The player stands
on the foot plates 90;91, t,hen moves the foot plates 90;91
with the legs back and forth on the tracks 30 alternatively.
As the foot plates 90;91 are alternatively moved, the slides
40 are respectively moved to stretch the linking-up cables
80;81. During the reciprocating motion of the foot plates
90;91, the stop blocks 75 are alternatively stopped by the
front and rear stands 10;20, and therefore the slides 40 are
prohibited from disconnecting from the tracks 30. The
drag resistance from the linking-up cables 80;81 can be
adjusted by turning the damping wheel 60 through the knob 61.
Because the slides 40 are respectively supported on the
needle bearings 32 and guided by the respective rollers 41,
the foot plates 90;91 can be smoothly and stably moved on the
tracks 30.
